INFORMATION
In case of third-party gas boiler:
When starting up the system in a cold climate, it may be
required to start up with a small water volume. To do this,
gradually open the heat emitters. As a result, the water
temperature will gradually rise. Monitor the inlet water
temperature ([6.1.6] in the menu structure) and make sure
it does NOT drop below 15°C.

If the installation of the unit has been done correctly, the unit will
start up during test operation in the selected operation mode. During
the test mode, the correct operation of the unit can be checked by
monitoring leaving water temperature (heating mode) and tank
temperature (domestic hot water mode).
To monitor the temperature, go to [A.6] and select the information
you want to check.
During a heating test run, the unit will start up in hybrid operation.
The setpoint of the gas boiler during a heating test run is 40°C. Keep
in mind the 5°C overshoot that is possible during boiler operation,
especially in combination with floor heating loops.
